In modern society women do (arguably) get the same rights for education, same opportunities for careers as men do. And they do use it, the number of women getting collage education has actually surpased the number of men. Also young women are outearning young men.

However women which do get collage education, which do have careers end up having less children their their less educated sisters even though they outearn them. Self admitely educated women become too smart to have children.

If woman does have just one kid, then she is passing on just half of her genes and just half of her upbringing. With just one child she is putting all of her eggs in one basket. If that child ends up childless because her son ends up being an inc3l or her daughter decides to stay childless or whatever... she is out of the pool.

So even when men willingly let women have all equalities and freedoms, do not stand in their way. Biology doesn't care, genes and upbringing which are the most fit are going to get passed on.

Not the "best" genes. Not the smartest, fastest, most beautiful... no the genes which are most fit.

So a couple of generatipns of doing this and we are back to Patriarchy. Not because evil men, hur dur... but because smart women were to smart to make kids.
